GENERAL DESCRIPTION

The DM9302 Fiber converter is complied with IEEE802.3 standards, and designed to convert data signal between 10/100 Base-TX and 100 Base-FX fast Ethernet.

Media converters are connected between Fiber cable and twisted cable segments with network and also the simplest way to interconnect any equipment’s 100BASE-TX / 10BASE-T to the 100BASE-FX interface network.
